E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
-To evaluate the efficacy of topically administered AG013 compared to placebo for reducing OM in patients undergoing chemoradiation for the treatment of head and neck cancer, as measured by the duration, time to development, and overall incidence of OM during the active treatment phase, beginning from the start of chemoradiation therapy (CRT) until 2 weeks following its completion.
-To determine the safety and tolerability of AG013 during the active treatment phase described above.
|
|
E.2.2 | Secondary objectives of the trial |
-To evaluate the effect of AG013 on patient-reported symptoms and analgesic use during the active treatment phase, and on the cumulative radiation dose administered before the onset of OM.
-To assess biomarkers and, in a subset of subjects, the PK profile of AG013.
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |

E.5 End points |
E.5.1 | Primary end point(s) |
Efficacy:
-Duration (in days) of severe oral mucositis (WHO grades 3 or 4)
Safety:

-Changes in vital signs and clinical laboratory parameters |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Duration of severe oral mucositis - evaluated twice weekly and on Day 14 post-CRT (end of active treatment phase visit)
Incidence of AEs and SAEs - evaluated twice weekly during treatment, on Day 14 post-CRT, then weekly for 4 weeks after completion of active treatment
Changes in vital signs and clinical laboratory parameters - evaluated weekly during treatment and on Day 14 post-CRT |
|
E.5.2 | Secondary end point(s) |
-Time to onset of severe oral mucositis (WHO grades 3 or 4)
-Incidence of severe oral mucositis (WHO grades 3 and 4)
-Duration of ulcerative oral mucositis (WHO grades 2, 3 or 4)
-Time to onset of ulcerative oral mucositis (WHO grades 2, 3 or 4)
-Incidence of ulcerative oral mucositis (WHO grades 2, 3 or 4)
-Cumulative radiation dose to development of severe oral mucositis (WHO grades 3 or 4) and ulcerative oral mucositis (WHO grades 2-4)
-Patient-reported pain as measured by Question 2 (mouth and throat soreness) of the Oral Mucositis Daily Questionnaire
-Use of analgesics to control oral pain measured as morphine equivalents
Pharmacokinetic and Pharmacodynamic:
-Assessment of biomarkers (primarily pro- and anti-inflammatory cytokines)
-PK profile of AG013 based on blood/serum samples and buccal smears in a subset of subjects
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
All WHO grade secondary endpoints are evaluated twice weekly and on Day 14 post-CRT.
Use of analgesics is evaluated twice weekly, on Day 14 post CRT, and weekly for 4 weeks after active treatment phase
OM assessments will be completed at the screening and baseline visit, twice weekly (no less than 48 hours apart) within each 5-day RT during the active treatment phase, at the end of active treatment visit, and weekly for four weeks during the short term follow-up phase. If OM has not decreased to less than grade 2, weekly OM assessments will continue until OM is a grade 1 or less.
Biomarkers are assessed at Baseline, Weeks 3 and 5 (on the last day of RT for that week), on Day 14 post-CRT, and at Week 2 of short term follow up phase |
